Your skin barrier breaks down every day. BioVer-X™ rebuilds it.
BioVer-X™ Enhanced Antioxidant Serum
A nightly base-layer serum built around BioVer-X™, a patented polyphenol that delivers 10x the anti-inflammatory protection of standard resveratrol. It targets the dermal layer where barrier proteins are made — not the surface.
SHOP BIOVER-X™ SERUMWhat happens at the base layer stays in the barrier.
Most serums deposit active ingredients on the skin surface. BioVer-X™ is engineered to penetrate to the dermal layer — the production floor where collagen, elastin, and ceramides are built.
Once there, it reduces the chronic low-grade inflammation that silently degrades structural proteins every day. This is not a temporary cosmetic effect. It is a measurable reduction in the signals that cause long-term barrier breakdown.
The result: skin that functions better over time. More resilient. More intact. Less dependent on products to look and feel the way it should.
Two women. One molecule. No shortcuts.
Katie is a biomedical scientist who spent a decade studying polyphenols in cancer research before realizing the compound she had been working with had a second life — in skin barrier repair.
Kristina is a skincare specialist who had already built a line of barrier-first formulas from her kitchen. When they met, they realized the ingredient and the philosophy were the same.
They patented BioVer-X™ themselves. They chose not to license it to a cosmetics conglomerate. K&K exists because they believe skin should need less over time — not more.
Stay in it.
New research. Product updates. Barrier science — explained in plain English.
